OILING SYSTEM.

Specification of Letters Patenti Patented Dec.10, 1912'.

Application filed January 17, 1910. Serial No. 538,345.

To all whom 'it may concern:

Be it known that I, CHARLES E. Wirrirsn, a citizen of the United Statesof America, residing at Detroit, in the county of Wayne and State ofMichigan, have invented certain new and useful Improvements in OilingSystems, of which the following is a specication, reference being hadtherein to the accompanying drawings.

This invention relates to an oiling system for maintaining a constant.level of oil in the crank ca se of engines employing the splash systemof lubrication and also for maintaining a constant level of oil in thecasing of the power transmitting mechanism where such mechanism forms apart of a unitary power plant, and the object of the invention is torovide simple and eiiicient vmeans for feeding measured quantities ofoil to the crank case or transmission casing in timed relation to thespeed of the engine, utilizing for such purpose a rotatable inember ofthe engine and thereby obviating the necessity for auxiliary pumps, orother means for elevating the oil, and further, to provide certain newand useful features in the construction, arrangement and combination ofparts, all as wilt be hereinafter more fully described rel'el ence beinghad to the accompanying drawings in which,

Figure l is a side elevation of an engine einbodyinr the invention withparts broken away to sillon the construction; JFig. 2 is a transversesection of the same substantially onv the line :1iof Fig. l, with partsbroken away to show the construction; Fig.

55 is a detail showing a portion of the en gine in side elevation withparts broken away to show the construction Fig. 4 is an enlargedsectional detail ot' the delivery tube or valve and adjacent parts; andFig. 5 is a sectional detail showing the scraper.

For convenience of illustration the invent-ion is shown as applied to afour-cylinder internal combustion engine but 'it will be understood thatthe same may be applied as well to` other types or classes of enginesemploying the splash system of lubrication in which it is essential inorder to secure the best results, to maintain the oil in the crank caseat a certain level. A casing for a power transmission mechanism is alsoshown as forming a part of the power plant which is especially designedfor autoniebiles, but it is obvious that the' invention' may be used inother constructions having a transmission casing adapted to contain oiland in which casin it is desirable to maintain an oil level to insurethe etlicient lubrication of the parts.

leferring to the drawings l represents a closed crank case of an engineWithin which the crank shaft 2 turns and is mounted in the usuahmanner.Formed integral with the bottom or lower side of the crank case l isan'oil chamber 3 into which the oil from the crank case may overflowwhen it reaches a level above the upper end of a stand pipe 4 extendingthrough the bottom of the crank case into the chamber and upward withinthe crank case to the height at which it is found desirable to maintaina level of oil in order that the most etlicient oiling of the bearingsand cylinders may be secured.

The greater the Speed ofthe en ine the more oil will bc consumed in theearings and will be splashed into the stand pipe and flow into thechamber 3. It is therefore desirable to feed into the crank casequantities of oil in proportion to the speed at which theengine isruiming so that at all speeds and at all times the desired level of oilwill be maintained in the crank case. The chamber 3 is utilized as anauxiliary supply tank and if a surplusageof Oil is put into the crankcase, it will simply flow back into this supply chamber through thestand pipe 4.

On the bottom of the chamber 3 is formed a duct 5 by casting a hollowprojection or rib upon the bottom of the chamber and this duct istapered toward the forward end of the chamber and at its rear end isformed into a tubular portion 6 Open at its forward end iio the taperingportion of the duct which tapering portion is open at its upper side toreceive oil from the chamber.

On the crank shaft 2 adjacent tothe rear end of the crank case issecured a. Hy Wheel 7 ol' any suitable form and construction andinclosing the fly wheel is a casing 8 which is bolted to a disk 9 formedintegral with the end of the crank case, said disk formin the forwardend of the casing. The sai casing is extended rearwardly, forming aninclosin casing 10 for aftransmission mechanism not shown), the interiorof which casing is separated from the interior` of the fly wheel casi 8,by a vertical wallv 1I in which is a sma'h hele 12 through which theoil'in tHe-transmission casirg may ovrow back into the' fly Wheelcasing, said'liole .portion 6 of the 'duct with its rear end pressedagainst the fl Awheel by a coiled s ring 15l inserted wit in the ductbetween tiie forward end oi the tube and a ledge 16 extending into theVduct from the wall thereof. .The fly wheel is faced off at its forwardsideso that the end of the tube 14 will fit closely against the same andform avalve to prevent the esca e of oil from the tube except when one othe vpockets is brought into registry with the end of the tube as thewheel 1s turned. The contact end of the tube is enlarged or flanged asshown in" Fig. 4 so that if the Wheel should come to rest with one ofthe pockets partially over the endof the tube, the flange will preventthe escapeof oil from the tube into the fly-wheel casing.

When one. of the pockets 13 is brought into alinement with the end ofthe tube it will receive a certain quantity of oil from said tube andwill can? the oil upward therefrom the oil escaping rom the pocket andbeing carriedv by centrifugal force around and uplon the periphery orouter face of the fly w eel as the wheel is turned rapidly. At the upperside of the fly wheel the casing 8 is enlarged or formedwith a chamber17 to receive a pivoted flap or scraper v18 adapted 'to engage and vridefreely upon the face of the yflywheel and to scrape or pick up fromsaidv face the oil which has been carried up thereon from the deliverytube 14. Leading from one end of the scraper 18 is a passage 19 whichopens intoV the ytop of the crank case 1 and thus the oil picked up bythe sbra er is conducted into the top of the cran case to replenish thesame. This passage 19 may be formed in the disk 9 as shown or it maybe aseparate tube or pipe if desired. Leading from the opposite end ofthesera r, is-a passage 20 which may be formed n the casln as shown ootherywise arranged to con uct part of the oil romrthe scraper intol theop of the transmission casing 10 where it will settle to thel bottblnthereof and maintain alevel of oil therein, any surplusage flowingthrough te hole 12 into the fly wheel casin where t will be a ain pickedup by the `ace of said wheel an delivered to the scraper.

The pockets-13, any desired nuniber of which may be used, form'measuring devices to receive certain quantities of oil from the supplychamber' and deliver the same to the scraper at the upper side of thefly wheel. The greater the speed of the engine the faster the fly wheelwill be turned and the greater will be the frequency of the receptionand discharge of oil from these pockets. Measured quantities of oilwill, therefore, be delivered into the crank case and transmissioncasing at a frequency proportionate to the speed of the engine andsuflicient oil, no matter what the speed of the engine may be,'willalways be delivered to said casings to maintain the proper level of oiltherein. i t
